Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130500, here are decompositions:

11 + 130489 = 130500
17 + 130483 = 130500
23 + 130477 = 130500
31 + 130469 = 130500
43 + 130457 = 130500
53 + 130447 = 130500
61 + 130439 = 130500
89 + 130411 = 130500

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 130,500 and was likely granted around 1872.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
